BRYANT H. BLOOD, OF HARTFORD, CONNECTICUT, ASSIGINOB TO PRATT & WHITNEY COMPANY OF NEW YORK, N. Y., A COR-FORATION OF NEW JERSEY;

GAUGE.

Application filed May 28,

To all whom it may concern:

Be it known that I, BRYANT H. :Bnoon, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Gauges, of which the following is a specification.

This invention relates 'to gauges and is particularly applicable to gauges of the op posed contact type, especially limlt gauges having two or more pairs of opposed con tacts or anvils. For performing certain gaging operations with this type of gauge it is desirable and often essential that the 1 gauge anvils be rovided with projecting gaging heads. It 1s an object of this invention to provide such a gauge wherein ga ng heads of a novel form project laterally 0 the gauge for the purpose stated. Also in the smaller sizes of such gauges, the distance between the opposed arms of the gauge is so small that the anvils cannot be assembled in the usual manner from the center outwardly. It is accordingly another ob ect of this invention to form the gaging heads of such shape relative to the openings within the gauge frame that the anvils may be assembled from the outside of the gauge inwardly, the heads passing through such openings.

Other and more specific objects of the invention will appear as the description proceeds.

Referring to the figures of the drawing:

Figure 1 is a side elevation of the gauge and its handle showing one of the gauge anvils and its adjusting mechanism in section, such section being taken on the line 1-1 of Fig. 3.

Fig. 2 is a front edge view of the gauge.

This invention relates to a gauge particu-.

ing application Serial No. 353,379, filed Jan. 22, 1920, the present invention however relating particularly to the anvils or contact members and the gaging heads thereon and the manner of assembling the same in small gauges.

In the drawing, 1 represents the main As illustrated, there are two pairs of op posed anvils 4 and 5 and 6 and 7 respectively. At least one member of each pair is adjustable, and preferably, as shown, both anvils are adjustable. I have illustrated the anvils 4 and 5 as provided with laterally projecting aging heads which extend beyond the gauge 'rame and are therefore free from interfer- 'ence by the frame with the work when taking a close measurement such as a measurement directly adjacent a shoulder. Also I have illustrated the anvils 4: and 5 as each being provided with a gaging head projectin laterally to one side only of the gauge, this construction being particularly applicable to the gauge shown as will hereinafter appear.

Each of the anvils, as for instance 4;, is lineally movable, and there are two independent adjusting devices, as in the gauge disclosed in the aforesaid application, which engage each anvil and which act in opposite directions thereon to adjust and lock it in adjusted position. Preferably, as shown these adjusting devices are in the form of screws 8 and 9. In the preferred embodiment of the invention these screws are held against longitudinal movement and have threaded engagement directly with the anvil. The two adjusting. screws, together with the major portion of the anvil, are positioned within an opening in the gauge body. In order to provide a simple and compact construction, this opening consists of two intersecting bores 10 and 11, one adapted to receive and fit the shank of the anvil, and the other adapted to receive and fit the exteriors concaved portion so as to be adapted to be engagedfby;thefsorews, whereby thejanvil is held from" rotation within the gauge and may be adjusted longitudinally and'lo'cked ingadjusted position. i Two separate pins '12 and 13 extending through transverse 'holes in the gauge body are adapted to serve respectively as abutinents for the screws 8 and 9. It will be seen that when the screws are tightened they bear againsttheir respective pins- 12 and, 13 and actin opposite direc- I anyiigjt hussecu ely locking it ag S t lin' l adj; tthefanyil nwardf the screwS is first leo'senegi It iejs r' w "9,;thn f screwed into 'al yfemteaat pair of anvils n 'Tprfe r e; [d5Twithjtheprojeetingheads 6 above 116 d toand therear pair. of anvils 6 and T i plain :g'a ging. surfaces In the smaller sized gauges, as the one illustrated, 5 l 's el s l tha hedi'st n bet [the 'gaging'farms 2 and 3, mustbe asi, d in th'e gaugejifroinithe outside in' we 11y...

When thef head fhas passed entirely through the opening-to a position between the arms 2"a11d3, the head is turned-to its latermdve'rnent. If'it isdesii'ed to derlto overcome this difli culty without al position with the screw threads 14 opposite the adjusting, screw opening, the pins 12 and 13 are set in place, and the adjusting screws are inserted to hold the anvils in position. It will be noted thatthe threads 14 for the adjusting'screwsare formed along the body portion of the anvil, and in order that the gaging heads may extend laterally of the gauge, 1 form these screw threads approximately atri'ght angles to the head 16 on the shank. Inthe assembled position, as seen in Fig. 3, the straight edges 16 of the gaging headsextendftranversely of the gauge frame in such manerfas to adaptsii'ch edgesto be readily used 'as gaging-elements. It will be noted that each 'such edge 16 is formed 'at. the apex or. meeting line of the front and endz'surface's of the head 16.. It willfurthermorelbe noted that the edge 16, of ,one anvil 4 directly opposite such edgeon the "anvil 5 whereby :such edges cooperate to form opposed gaging elements. Also, as hereto fore stated,the free outerends'oi, the heads 16 extend laterally ofthe gaugebeyond the to make a measurement which oannotwellbe reached by the front edges 16; of the heads.

When two pairs of cont-acts areprovided, as shown, the gauge can be usedas a.go

l gauge frame :whereby sucli' ends may be used and no go limit-gauge,andthe contacts 1 can be readily changedfordifierent toler ances'. Afte'r'the gauge has been adjusted in the to ol room it can lee sealed by placing sealing wax in the several'bo-res 10 'andI-II.

In Figs. 1 and 4, I ha ve illustrated the gauge as provided with a novel form of handlewhioh though not apart of the present invention and not claimed herein is particularly adapted for use with a gauge of this type. This handle preferably comprises a hand hold 17 ofwoodorother heat insulating'material and a pair of gaugecl'ainps 18 and 19 secured together aiscrew 20;

As will be noted the clamp 18 is removable from the clamp 19 whichis'socketedin the handle. It will further be notedthat the handle may be secured toq. any oneiofthe straight sides 21 of thelga-ugeirame in such manner as to hold the gauge in any position desired. The handle illustrated ,not only provides a convenient ineans for holding?the small gauge but also provides a; heat insus lating means wherebythe opera-toris liand never comes int-o contact with the gauge frame.

Thegeneral construction described and illustrated herein constitutes a gauge wherein the objects sought :are ,fiilly attained in a very simple and substantial manner, and. while the drawing illustratesonly one prac tical application of the invention, it should Inn be understood that the same is capable of other applications and may other forms.
